 ABSTRACT: Most people get their surnames from their fathers. The surnames therefore well exhibit patrilineal heredity. Strict patrilineal heredity is also obeyed by parts of our genome, the Y chromosome non-recombinating portion. Therefore, men sharing a surname are expected to have similar Y chromosomes. However, association between surnames and Y chromosomes is always weak or absent due to the complicated social behaviors of surnames, e.g., various founders for a surname, surname changing, and non-paternity events. To set up better association, the family genealogies in combination with Y chromosomes should be used in historical anthropology studies. Two kinds of markers on Y chromosomes, single nucleotide polymorphism (SNP) and short tandem repeat (STR), are widely used in setting up the Y chromosome genealogy and estimate the time. Y chromosome studies show strong power in resolving many doubtful cases existing for hundreds of years. Application of Y chromosome analyses in the family genealogy studies will be a most important part of historical anthropology researches.

Key words: Surname; Y chromosome; Single nucleotide polymorphism (SNP); Short tandem repeat (STR); Family genealogy.

摘要： 人们的姓氏大多继承自父亲，而Y染色体是严格的父子相传的基因组片段。所以姓氏与Y染色体的遗传应该是平行的，有共同姓氏的男性可能有相同或相近的Y染色体类型。然而，多起源、改姓、非亲生、从母姓等社会因素弱化了某些姓氏与Y染色体的关联，此时家谱研究可为厘清父系血缘提供线索。Y染色体上稳定的SNP突变可以永远在父系后代中流传，可以构建可靠的父系基因谱系；而其上突变较快的STR位点又可以用以估算时间。因此，Y染色体可用以研究很多姓氏宗族的历史，甚至千百年前的历史疑案。重建姓氏、家谱与Y染色体的关系必将成为历史人类学研究的重要内容。
